Specification of Letters Patent. Patented June 1912,

Application filed August 10, 1910. Serial No. 576,546.

To all whom it may concmmq Be it known that I, WALTER P; MURPHY, acitizen of the United States, residing at Chicago, in the'county of Cookand State of Illinois, have invented certain new and useful Improvementsin Car-Roofs, of which the following is a specification.

In certain car roofs comprising metallicthey hold the sheets down on thesubstructure. This tendency. of the sheets to slide longitudinallycauses a strain 'upon the nails, clips on other fastening means in thedirection in which their-resistance is least, as t-h'e cli'ps tendto-turn outwardly about their lower endsa-sfulcra. 1

One of the objects of any invent-ion is to eliminate the use of nailsand of clips secured to the molding orside of the car to hold-the outeredge of the sheet down, except; at the searns-bet-weenlthe sheets.

Anotheri'object of my invention is to pre: vent 'pucl tering of thereofsheets. Still-anotherobject of my .invention is to permit" the endportion of. the sheet to Work up and downover' a fascia having an upperrounded corner; and with these and minor objects in view, my inventionconsists of theparts; and combination of parts as willbe hereinafterpointed out.

'In-thedrawing, Figure-1 is a side elevation ofa car, partsbeing brokenaway, with my invention embodied, Fig. 2 is a section on the line 2-9,'Fig. 1; Fig.3 is a detail sectional viewiof a carat the eaves showing amodified form-of roof clip; Fig. 4 is a perspective view of the clipshownin Fig. 3;

Fig. 5 is a'detai1-sectiona1 view of a roofing sheet having the clipsecured on its under face; Fig. 6 is a: detail sectional-view of a.

sheets. down over the caves of the car and secure the bent over portionto a fascia or to the side of the car by means of nails, clips, etc, butit has been found that this results in the tearing of the sheets" at theeaves, where they are bent over, inasmuch as the tendency of the sheetsto slide longitudi nally is resisted, thus permitting water, snow, dustand cinders to work up under the roofing sheets thence into, the car. Iovercome these objections and the faulty constructi'on by riveting orotherwise suitably securing to the. roofing sheet 2 clips 8, conformingto the bend of the sheet at the eaves as shown in Fig. 1 One arm of theclip is secured to the main body or portion of the sheet, while theother arm is secured to--the turned down portion 9 of the sheet.

10 is a roof 'seam clip provided with a hood 11 constructed to close theopen. end of the seam 12 and cover a portion of the seam as shown inFig. 1. The apron of the seam clip is wide enough to bridge the gapbetween the turned down portion of the sheets at the seam and isprovided with wide spreading side wings 13, which project over the downturned portion 9 of the roof sheets, as shown, thereby assisting theclips 8 in holding the roof sheets in their bent position.

The wings or arms 13 are slightly thinner Y thanfthe apron of the seamclip as shown in Fig. 7, in order that the under face of the apron maybe secured snugly against the fascia or side of the car, the extrathickness of the apron serving as a spacing block for the wings 13, thusspacing tl'iem from the fascia or side of the car to permit of theportion 9 of the roofing sheets occupying 13 is inserted in. the upperopening, the

body thereof passing between the side edges of adjacent sheets and abovethe down turned ends of the sheets which overhang the eaves of the car,whereby the clip is secured to the car at the eaves between thedown-turned ends of the sheet. The bolt,

nail or screw 13 is passed through the lower fiopies of this patent niaybe obtained for be secured to the under face of the roofing sheets asshown in Fig. 5; and it may be provided with a reinforcing rib 1 1 asshown in Figs. 3 and 4. The roofing sheets may be dohbled baek at theouter end and have sheets puckering, curling up or outwardly,

and further eliminate the liability of the root sheets tearing, ashappens in the constructions where'th end of the sheet is nailed orotherwise rigidly secured to the fascia or side of the ear. I Anotheradvantage of this construction is that the end portion of the sheet isfree to work up and down over the rounded corner of the fascia. T hewings 18 ot' the roof seam clip hold the downwardly bent portion 9 frombending outwardly or curling at the side edges of the,

sheet. I

The fascia 15 extends outwardly far enough beyond the cliis and roofsheets to protect them against side scraping and is of such shape thatwater will readily run off of it free trourthe side of the car.

IV hat I claim is 1. A car roof comprising metal sheets 'flexiblvconnected by interlocking flanges extending 'from the eaves to theridge, the outer portion of each sheet being bent down over theeaves,and means secured to each sheet in the outer bent down portion tomaintain the angular relation of the bent portion relative to the mainbody portion of the sheet.

2. A car root comprising meta-l sheets flexibly connected byinterlocking flanges -extendingfrom the caves to the ridge, the outerportion of each sheetbeing rounded and bent down over the eaves, afascia having a rounded upper corner braces secured in the rounded andbent down. portion of the sheets to maintain the shape of this portheouter portion OfWlllCll is bent down to form an eaves bend at rightangles to the main portion of the sheet, of brackets secured in saidbend to stiffen the bent port-ion and maintain the angular-relation be--tween said bent portion and the main portion of the sheet.

4.' In a car roof comprising roof sheets movably secured thereon havingdownturned ends overhan ing the eaves, eaves clips arranged at the ointbetween adjacent) roof sheets to overlie the same, said eaves clipscomprising base portions and wing portions extending from the outeredges of the base portions and overlapping the down-turned ends ofadjacent roof sheets, said base portions being of greater thickness thanthe wing port-ions, wherebythe wing portions are spaced from theroof'sheets and loosely secure the latter at the eaves corners thereof.

5. In a car roof comprising roof sheets movably secured thereon havingdownturned ends overhanging the eaves, eaves clips arranged at thejoints between adjacent roof sheets to overlie the same, said WALTER P.MURPHY. Witnesses:
